Microneedling

Microneedling at Dallas Plastic Surgery Institute uses a precision pen device to create controlled micro-injuries in the skin, triggering the body's natural collagen repair cascade. The treatment addresses acne scars, enlarged pores, fine lines, uneven skin texture, and dull complexion. A numbing cream is applied prior to treatment to maximise comfort. A series of three sessions spaced four to six weeks apart is recommended for optimal results, with PRP enhancement available as an add-on.

Microneedling offered at Dr. Sam Jejurikar's Dallas practice is a controlled collagen induction therapy that uses a motorised pen device fitted with a sterile disposable cartridge of fine medical-grade needles. The device creates thousands of microscopic vertical channels in the skin at calibrated depths — typically 0.5 mm to 2.0 mm depending on the treatment zone and clinical indication — without removing skin tissue. Each micro-injury initiates a localised healing response: platelets aggregate and release growth factors including PDGF, TGF-β, and VEGF; fibroblasts are recruited and upregulate collagen and elastin synthesis; and the remodelling phase over four to eight weeks deposits new collagen in the papillary and superficial reticular dermis, progressively improving skin structure. The micro-channels created during the procedure also transiently increase transcutaneous permeability, making this the optimal window for topical delivery of active serums. A hyaluronic acid serum is applied and worked into the micro-channels during treatment to provide deep dermal hydration and support barrier function as healing progresses. For patients seeking an amplified biological response, platelet-rich plasma (PRP) can be prepared from a small autologous blood draw and applied through the channels — the concentrated growth factor mixture provides an additional fibrogenic stimulus on top of the mechanical injury signal. Clinical indications at this Dallas plastic surgery practice include atrophic acne scars (rolling and boxcar subtypes respond particularly well), enlarged and congested follicular openings, fine surface lines, rough or irregular skin texture, early post-inflammatory hyperpigmentation, and generalised skin dullness. Needle depth is adjusted zone by zone to match the skin's anatomical thickness — shallower settings of 0.5 mm for the periorbital region, and deeper passes of 1.5–2.0 mm for the cheek and jawline zones where acne scar remodelling is the goal. A standard microneedling session at Dallas Plastic Surgery Institute runs approximately 60 minutes including numbing time. A series of three sessions spaced four to six weeks apart is recommended as the base protocol for most skin concerns, with additional sessions or maintenance treatments scheduled based on clinical response. Patients are advised to use SPF 50+ daily throughout the treatment series and to avoid active retinoids and exfoliants for 48 hours before each session.
